Quin began training as a professional wrestler in 2002. Initially working in Ireland, and occasionally teaming with her brother using the ring name Rebecca Knox, she soon began wrestling across Europe and North America on the independent circuit for various promotions. She most notably competed in Elite Canadian Championship Wrestling and became the inaugural SuperGirls Champion in 2005.
In 2006, Quin had a severe head injury during a match which kept her away from wrestling for several years. She returned 2012 and signed a contract with WWE in 2013, assigned to the developmental territory at NXT. Following her push to WWE’s main roster, she became the inaugural SmackDown Women’s Champion at Backlash 2016 and has held the title four times.
In 2018, Lynch transitioned to a more aggressive character starting at SummerSlam, when she attacked Charlotte Flair, presenting herself as an unfairly treated underdog and dubbing herself “The Man”, resulting in a large increase in her popularity. In 2019, she won a Royal Rumble match, and at WrestleMania 35 won both the Raw Women’s Championship and SmackDown Women’s Championship, making her the first woman to hold both titles simultaneously and a four-time WWE women’s champion.
She lost the SmackDown title the following month but then set the record for the longest reign as Raw Women’s Champion at 398 days until going on a hiatus due to pregnancy in May 2020. In August 2021, Lynch returned at SummerSlam to confront SmackDown Women’s Champion Bianca Belair, whom she would defeat seconds later to become a four-time SmackDown Women’s Champion.
In September 2023, Becky Lynch defeated Tiffany Stratton on an episode of NXT to win the NXT Women’s Championship, and therefore, become WWE’s sixth Women’s Grand Slam Champion.
